WebDiscuss the normal forms (CNF or GNF) of a grammar with productions: S → B C C B B → c B c C → c C ϵ Same request with the following grammar: S → B C C B B → c B c C → c C c I applied the rules to convert a grammar into its normal form and I think that both are CNFs. For the first grammar: S → B C C B C ′ B c B → C ′ B c WebA context free grammar is said to be in chomsky normal form (CNF) if all its productions are of the form-. A → BC or A → a. where A, B, C are non-terminals and a is a terminal. From here, we infer-. To be in CNF, all the productions must derive either two non-terminals or a single terminal. CNF restricts the number of symbols on the right ...
